Letters Patent No. 100,094, dated February 22, 1870.

IMPROVEMENT IN BOLT-FEEDERS P OR- MILLS.

The Schedule referred to in these Letters Patent and making part'of the same.

Toall whom it may concern L Be it known that I, BENJAMIN A. WING, of Galesburg, in the county of Kalamazoo, in the State of.

in which an incision, a b, Fig. IV, is made in the difeeder, a door, M, has been made in the lower part of the cylinder, large enough fora man to get in with his rection of the radius, and about to five-sixth of its length. Then starting from the end a of this incision,

-a circular cut, a c, is made, reaching about as far as which, it divides into an upper and a lower compartment. If the upper compartment be filled with meal and the machine put to work, the effect will be similar to that of a screw of Archimedes. The upper edge of the screw-shaped disk will gradually cut off from the meal'overit, and make it pass into the lower compartment, whence it will fall in are'gular stream through the discharge-spout F into the bolt. H Y

1 The opening a a bi), Fig. V, through which the meal passes from one compartment into the other, may be varied by means of the following arrangement:

A lever,' G H, having its fulcrum in the wall of the cylinder E, and provided on both ends with a horizontal eye, can be screwed down on the end outside of the cylinder by means of a nut on the bar I, which is fastened to the frame. At the same time, the inside'end will go up, the eye having same play on the shaft 0, r

and by pressing under a ring of hard wood, K, which lies tight under the plate A, it will close partly the 1 .opening a a b b, which will reopen by elasticity when the nut is loosened.

An arm, L, is fastened to the upright shaft alittle over the. bottom of the cylinder, for the purpose of scraping off the inealfrom the hott0m,.so that it will fall through the discharge-spout into the bolt.

For the purposeof. removing obstructions under thehand.

The advantage obtained by this kind of I feeder is double; first, the greatest possible regularity in feeding; and second, self-regulation in asfar as when the bolt is turning more rapidly, the feeder, which is driven by the same machine, will increase its velocity, and the meal will be fed quicker.

What I claim as 'my invention, and desire to secure by Letters Patent, is-

1. In the bolt-feeder here shown, the helical metallic plate A, in combination with the cylinder E, when said parts are constructed and arranged to operate as herein shown and described 2. In combination with the above, the ring K and regulating device G H I, when arranged to operate as herein shown and set forth.- f
